COAL BURNER.

Application led January 8, 1923. Serial No. 611,421.

To L7/Z whom t may concern:

Be it known that we, JAMES CHARLES ORB and CHARLES Twnnnin CLUrr, bothof the city of Winnipeg, in the Province of Manitoba, Canada, haveinventedY certain new and useful 4Improvements in Coal Burners7 of whichthe following is the speciication.

The invention relates to improvements in coal burners and an object ofthe invention is to provide a device for insertion in the fire pot of afurnace and which is particularlyV constructed for use in the burning ofsoft coal in they furnace, the device being constructed to supply airfor combustion purposes and to separate the fire pot into two lirecompartments, such latter permitting of the alternate firing of the coalin opposite sides of the fire pot.

A further object is to construct the appliance such that it can bereadily inserted in the furnace through the tire door and such that itis entirely supported by the grate bars.

A. further object is to construct the apv `divisionalmember lwhichpasses in al direcpliance in a simple,V durable and practical manner andsuch that/it can be produced l and installed at a comparatively smallcost.

With the above` more important objects 'in view the invention consistsessentially in the arrangement and construction of parts hereinaftermore particularly described and later pointed out in the appended claimsreference bein'g'had tothe accompanying drawing in which:

Fig. 1 is a perspective view of the device. 1

Fig. 2 is a face view divider.

Fig. 3 is a horizontal sectional view through the hollow post, thesection passing` through the side channels.

ig. 4 is a vertical sectional view centrally through the appliance as itappears in the fire pot, the divider being shown in side elevation.

In the drawing like characters ofireference indicate corresponding partsin the several figures.

In the burning of soft coal considerable care has to be exercised inorder to get the best results ,from the same and also to preventexplosions in the furnace. We have ofthe double winged i devised theburner herein described for insertion in the customary fire pot 1 of thefurnace, the burner being located centrally lof the furnace and havingthe baselthere'of resting on thegrate barsV 2.1 Thelburner presents ahollow body or post 3 having a centrally disposed vneck 4 which ares outand terminates at the bottom in an enlarged base 5 and has the upper endterminating in a hollow ball or sphere 6. The ball at spaced pairs ofvertical flanges 8 and 9- cast integrally therewith and forming verticalchannels or guides 110 and 11, the lower ends of the guides being closedby the flaring portion ofthe base."v y Associated 'with the' post weprovide a is adapted to seat on the top of the ball or sphere and theinner edges of the wings are `'designed to, slidably enter the guides"or channels 10 and 11 of the post. By forming thisr divisional memberlin this way one can first 'insert the post through the ire door" andlocate it properly on the grate bars, then he can insert the divisionalmember and place it in position on the post and in this connection it isadvisable to have the divisional member passing in a direction from thefront to the back of the furnace as this makes it a very easy matter tofire the coal used to either side of the fire pot. Y

When the divider is in place within the furnace the ball is above thecoal level and the lower edges of the wings are above the grate bars,whilst the ends thereof are entirely clear of the inner side of the firepot.-

The

cient air, provided through the openings 7,r

to provide a combustible mixture which ignites. This prevents anypossibility of eX- plosion.

Gradually the coal in the compartment will come to a nice even glow andwhen it has burnt down one throws fresh coal into the other side of thefire pot. The gases of this fresh coal are distilled out by the heat ofthe lire in the other` compartment and, mixing with the air, becomeignited in the combustion chamber.

The operation of alternately firing in opposite sides of the fire pot is.continued each time new coal is placed in the furnace.

`We might also mention that theburner is made of cast iron and hasfairly thick walls so that it becomes very hot and accordingly assistsin distilling out the gas and also in heating, to a high temperature,the air supplied through the grate bars and out the openings 7 to thecombustion chamber.,

lVhat we claim as our invention is:

l. A coal burner for insertion in the fire pot of a furnace,-comprisinga hollow post having the base thereof resting on the furnace graterbarsand having the upper end thereof closed and provided with a pluralityof'air outlet openings communicating with the combustion chamber, and aremovable divisional member carried entirely bythe y upper end of thepost and extending across the fire pot in an elevated position above thegrate bars and dividing the fire pot into two ring compartments. y

2. A coal burner for insertion in the ire pot ofa furnace, comprisi-ngaVhollow post positioned centrally of the fire pot and having the lowerend thereof resting on the grate bars andthe upper end communicatingwith the combustion chamber of the fur- .firing compartments.

3. fr coal burner for insertion in the fire pot of a furnace, comprisinga hollow post positionedcentrally of the fire pot and having the basethereof resting on the grate bars and the upper end thereof terminatingin a perforated ball, an elevated divisional inember crossing the firepot and dividing the same into two firing compartments and having thelower edge thereof clear of the grate bars, said divisional member beingremmable and hung from the ball and being prevented from rota-tionaround the post.

il. A coal burner for insertion in the iire pot of a furnace, comprisinga hollow post positioned centrally of the lire pot and having the lowerend enlarged and resting on the grate bars and the upperA end closed andperforated, and diametrically opposed pairs of vertically extendingspaced Aflanges provided on the post and forming vert-ical giudeways atthe opposite sides thereof.

5. The combination with a hollow perforated post for insertion withinthe ire pot of a furnace, said post being provided with diametricallyopposing vertically 'extending guides, of a divisional member insertiblewithin the fire Ypot and elevated above the grate bars thereof anddividing the same into two firing compartments and in the form of a pairof wings having their inner edges adapted to be receivedwithin theguides, the-said wings being connected by a strap passing overvthe upperend of the post and supporting the said divisional member. y 5 y Signedat Winnipeg, this 8th day of December, 1922.
